    Description

      Hi, 

      I updated Jenkins from 2.19.4 to 2.60.1. Then I cannot use 'SSH Plugin' anymore.

      On already configured 'SSH sites' in admin configuration, I have an 'ERROR' link under 'User Name' field. clicking on it gives a stack trace with 

      java.lang.ClassNotFoundException: sun.reflect.ConstructorAccessorImpl coming from com.jcraft.jsch.jce.AES256CTR.init,...javax.crypto.Cipher.chooseProvider...

      When adding a new SSH site configuration, the same error appears when losing focus (by clicking somewhere else) while editing the 'User Name' field.

          zendev please provide basic information:

          • which Java are you using (1.7 / 1.8 / 1.9 / OpenJDK / Oracle )
          • which particular RHEL6 version

          If you revert Jenkins to 2.19.4, is the bug still visible?

          Could you try to reproduce the bug on separate, vanilla Jenkins installation on the same machine?

          Java 1.8 used.
          The problem was solved by disabling some security settings (but now some admin security warnings are displayed in Jenkins).

          So this could be easily caused by any change between 2.19.6 and 2.60.1

          zendev Can you quote the admin security warnings you get?

          Additionally do you think we can close this ticket?
